This invention relates 'to' an improved flare bracket for carrying flare candles on 'the tips of" the wings of an, airplane or on other parts for night'flying.

The principalobjecft' of the invention is toprovide a device" of this kind wherein proyision is made for mounting a flare candle in air-approximately horizontal position with its lit end to the rear; for

suitably adjusting the flare candle relative to its bracket as necessitated by the'diiterent positions which the brackea'has' to be fastened for different installations,

and where it is desired'to' tilt the candle slightly with its shield so that'illumination ahead may be secured; for somounting. and I shielding the flare candle to eliminate, the

hazard of tire; and ioradjustin the shield or guard to protect-the pilot from the'glare fleetthe light of the ca'ndle.

The foregoing and other minor objects of the invention a're set'forth in the 61- lowing detailed description, wherein reference is made to "the accompanying ings, in which:-.-

The flare bracket'n ia-y be mounted inany one of ainumberotplaces but is ordinarily carried: on the under near the tip of the wing and 'adjacent'the outer extremity as shown in Fig. 1. The structure is carried by a support 10 suitably bolted adja-- cent a rib of the aerofoil 11, and in such close proximity with the skid 12 as to avoid contact with the ground in case the airplane rocks sidewise in landing, or taking off. The bracket proper is indicated at 13 and is suitably of sheet metal construction with a streamline contour to minimize head resistance. The bracket is pivoted at 14 to the support 10' to swing on a horizontal axis parallel with the leading edge of the wing to secure the proper positionin of the flare candle carried thereby regar less of the angle of incidence of the supporting surface on which the bracket is carried, the

purpose being ordinarily to have. the flare candle in approximately horizontal position In some instances the candle is tilted:with

it most clearly appears in. Fig. 4, the support 10 has depending wings 15 in which are provided circumferentially arranged openings 16 into any one of which a-sthd 17 on the free end of a leaf spring 18 is arranged to project. The springs 18, of

which there are two, one on each side ofthe bracket 13, are suitably secured at theirin ner ends by the rivets 14c constituting the pivotal connection between the support 10 and the bracket 14. To adjust the bracket, it i's'necessa ry only to (psenga-ge the studs 17 by spreading the lea can be done by hand since the outer ends "oft-he springs are turned out to provide finger pieces 19). The bracket 13, hasa flare 21 by turning the win 11115252. The holder is provided with direc "electrical connection at 28 and 24 by wires and 26 extending I along the wings to the cockpit where the Fig. 1 is a perspective view of the end of an aerofoil showing the flare bracket-- of our invention moiin'ted' thereon.

In this way, in the use of the flare bracket on different types of planes, the proper adjustment of the guard will eliminate fire hazards and also avoid a glare being communicated to the pilot from the burning candles. parent that in any position of forward and back adjustment of the flare bracket, necessary in bringing the flare candle to approximately horizontal position, because of the angle of incidence of the wing or inclination of the part on which the bracket is mounted the lateral adjustment of the guard will effectually prevent the communisprings 18 which It is ap catidn ra 331m and at the Same time eliminate the fire hazard.
